- Variables such as CC, CXX and related variables are usually assigned in core class like gcc.bbclass. For example, CC is assigned this specific value:
CC = "${CCACHE}${HOST_PREFIX}gcc ${HOST_CC_ARCH}${TOOLCHAIN_OPTIONS}"
If you use the += operator to add flags to the CC variable early in your recipe, your changes will be overwritten and lost because BitBake applies class assignments to CC at a later stage, which replaces any previous modifications.
We should use :append operation to ensures that additions are applied to the final value, after all assignments from core classes have been processed. As a result, when you want to extend variables that may be set in core classes (like CC in gcc.bbclass), you should use the :append syntax to guarantee your changes are preserved in the final build environment.
- Using CFLAGS is the standard way to pass compiler flag for C projects.
- The Makefile of the project doesn't respect to append to CFLAGS so added 0006-make-CFLAGS-appendable.patch to make CFLAGS appendable.

Subject: [PATCH] Allow extra CFLAGS via EXTRA_CFLAGS variable
|
|
|
|
This patch introduces an EXTRA_CFLAGS variable to the Makefile, which is
|
|
appended to CFLAGS. This allows users or external build systems to pass
|
|
their additional compiler flags.
